This paper describes the evaluation on numerical confusion over ternary regular finite equations about methods. Are rarely used, while the simple Euler’s technique is popular amongst researchers. We compare four explicit methods: Euler’s, Heun's methods, and polygon, including the honor analytical, is the accurate answer and value about external records regarding the simulation. The carelessness within analytical then numerical are moderate by way of the comparison along half previously...

Continuity equation for wave modeling is still being developed. There are quite a lot of versions of this equation. This research formulates continuity equation in a simple form to simplify its numerical and analytical solution. The formulation of the continuity equation is done by performing mass conservation law in a water column with free surface and by performing weighted total acceleration. Then, the continuity equation is performed along with the surface momentum equation and completed...

Via Rindler's coordinate transformation, wave equation in frame moving at uniform acceleration $a$ along x axis becomes $\frac{\partial^2 \Psi}{\partial x_a^2} + \frac{1}{x_a+\frac{c^2}{a}}\frac{\partial \Psi}{\partial x_a} + \frac{\partial^2 \Psi}{\partial y_a^2} + \frac{\partial^2 \Psi}{\partial z_a^2} - \frac{c^2}{a^2(x_a+\frac{c^2}{a})^2}\frac{\partial^2 \Psi}{\partial t_a^2}=0$. The equation reduces to the normal wave equation when acceleration $a=0$, thus it is a generalization of the...

Owing to the need of estimation and control of purity of air with respect to different gases, various types of mathematical models can prove to be highly useful. To be tune with this, an attempt in the form of development of a mathematical model to account for vegetation effect on atmospheric carbon dioxide (CO 2 ) and oxygen (O 2 ) has been presented in the paper. The model uses the numerical solution of various differential equations such as Poisson’s equation, drift- diffusion equation,...

In this paper authors study the customer’s preference of street shops to other eateries using Fuzzy Relation Equations (FREs) and Neutrosophic Relation Equations (NREs). We have constructed a new type of FRE and NRE called the new average FRE and new average NRE. This study is based on interviews /discussions taken from 32 tuck shops in and around Tambaram. This paper is organized into five sections. In section one we just recall the working of FRE and NRE.

The main objective of the present article is to study the oscillatory behavior of conformable fractional generalized Lienard equations. We obtain some new sufficient conditions that guarantee all solutions are oscillatory by using Riccati transformation technique. Suitable examples are inserted in order to illustrate the effectiveness of our obtained results.

In this short paper, the one dimensional wave equation for a string is derived from first principles. This paper was written in manuscript form in 1985 and was recently rediscovered by the author and is presented for the first time. This example draws from a question in a 1979 mathematical physics text by S.S.Rangnekar and R.H.Enns.

The perturbation equation of masseless fields for Kerr-de Sitter geometryare written in form of seperable equations as in [17] called the Angular Teukolsky equation. The Angular Teukolsky equation is converted to General Heun's equation with singularities coinciding through some confluent process of one of five singularities. As in [4, 16, and 17] rational polynomials of at most degree six are introduced. AMS Subject classification: 33XX.

Analytical solution of Laplace equation using variable separation method, consists of two velocity potentials. However, only one component has been used. This research used both velocity potential equation components. With the potential equation, water wave surface equation and the related wave constants were formulated using kinematic free surface boundary condition and surface momentum equation. The characteristic of water wave surface that was produced was observed, both in deep water and...
